1 Introduction

In the context of the paper “An experimental validation of architectural measures for cloud-native quality evaluations” experiments have been run to investigate relationship between architectural measures (measured at design time) and runtime measures (measured at runtime). The results of these experiments are reported in the following and can be accessed in raw form at:

2 Results
